Abstract
An apparatus includes a screen configured to be positioned on a vehicle exterior and a housing associated with the screen. The housing is comprised of a first material that is electrically conductive and thermally conductive and a second material is positioned to extend between an exterior surface of the housing and a vehicle structure, wherein the second material is thermally conductive.
